Drop - remove code for Internet Explorer

[jcfilben]

Evaluate if we can remove the following block of code from Drop/StyledDrop.js:

  /* IE11 hack to get drop contents to not overflow */
  @media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
    display: flex;
    align-items: stretch;
  }

We should be able to remove this since we are no longer supporting internet explorer but we should confirm across browsers (Safari, Chrome, and Firefox) that removing this doesn't have any unexpected consequences.

Hello @jcfilben,

I manually tested if there was an issue by removing the code and I couldnt see any, you can check it out from the screenshots that I posted in the pull request, however, a lot of snapshot tests are failing.
